采用毛细管区带电泳法建立了复方丹参滴丸(Compound Danshen Dropping Pill,CDDP)的指纹图谱.以50 mmol/L 硼砂-200 mmol/L 硼酸(体积比为1∶1,含1.1%(体积分数)三乙胺)为背景电解质溶液,采用未涂层石英毛细管(75 cm×75 μm,有效分离长度63 cm),运行电压18 kV,紫外检测波长290 nm,以原儿茶醛(protocatechualdehyde,PAH)峰为参照物峰确定8个共有峰,建立了CDDP的毛细管电泳指纹图谱(capillary electrophoresis fingerprint,CEFP).用系统指纹定量法评价CEFP所反映的CDDP质量,依据系统指纹定量法划分10批CDDP的质量级别,仅有1批含量偏低.系统指纹定量法可以对中药及其制剂进行较好的全质量控制,所建立的CEFP具有较好的精密度和重现性,为CDDP的质量控制提供了新的参考.
